Magma oozes are living pools of molten rock. They roam the borders of the Plane of Earth and Plane of Fire, and on the Material Plane they sometimes arise spontaneously from strange magic, usually in the vicinity of volcanoes. Magma oozes avoid water, and if forced into enough of it, they become encased in a cooled stony shell, unharmed but immobilized, waiting indefinitely until the water retreats.
A typical magma ooze grows to 10 feet across and is about 6 inches thick.
Differing types of molten stone and the nature of the magic that created them can influence what types of magma ooze form.
burn (2d6, DC 19)
constrict (2d6+13 plus burn)
Lava Body — The magma ooze is formed of molten rock. Whenever a creature strikes a magma ooze with a weapon, that weapon takes 4d6 points of fire damage unless the attacker makes a DC 19 Fortitude save. Damage caused to weapons in this manner is not halved, but hardness does help prevent some of the damage dealt. The save DC is Constitution-based.
Burn
(2d6, DC 19)
Ex
from Universal Monster Rule
A creature with the burn special attack deals fire damage in addition to damage dealt on a successful hit in melee. A creature affected by the burn ability must also succeed at a Reflex save or catch fire, taking the listed damage at the start of its turn for an additional 1d4 rounds (DC 10 + 1/2 the attacking creature's racial HD + the attacking creature's Con modifier). A burning creature can attempt a new save as a full-round action. Dropping and rolling on the ground grants a +4 bonus on this save. Creatures that hit the monster with natural weapons or unarmed attacks take fire damage as though hit by the monster's burn attack and must make a Reflex save to avoid catching on fire (see page 444 of the Pathfinder RPG Core Rulebook ).
Constrict
(2d6+13 plus burn)
Ex
from Universal Monster Rule
A creature with this special attack can crush an opponent, dealing bludgeoning damage, when it makes a successful grapple check (in addition to any other effects caused by a successful check, including additional damage). The amount of damage is given in the creature's entry and is typically equal to the amount of damage caused by the creature's melee attack.
Split
(cold and slashing, 8 hp)
Ex
from Universal Monster Rule
The creature splits into two identical copies of itself if subject to certain attacks or effects. Each copy has half the original's current hit points (rounded down). A creature reduced below the listed hit points cannot be further split and can be killed normally.
